Highlights for this merge window: * The whole caching of module code into huge pages by Mike Rapoport is going in through Andrew Morton's tree due to some other code dependencies. That's really the biggest highlight for Linux kernel modules in this release. With it we share huge pages for modules, starting off with x86. Expect to see that soon through Andrew! * Helge Deller addressed some lingering low hanging fruit alignment enhancements by. It is worth pointing out that from his old patch series I dropped his vmlinux.lds.h change at Masahiro's request as he would prefer this to be specified in asm code [0]. [0] https://lore.kernel.org/all/20240129192644.3359978-5-mcgrof@kernel.org/T/#m9efef5e700fbecd28b7afb462c15eed8ba78ef5a * Matthew Maurer and Sami Tolvanen have been tag teaming to help get us closer to a modversions for Rust. In this cycle we take in quite a lot of the refactoring for ELF validation. I expect modversions for Rust will be merged by v6.14 as that code is mostly ready now. * Adds a new modules selftests: kallsyms which helps us tests find_symbol() and the limits of kallsyms on Linux today. * We have a realtime mailing list to kernel-ci testing for modules now which relies and combines patchwork, kpd and kdevops: - https://patchwork.kernel.org/project/linux-modules/list/ - https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/README.md - https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/kernel-ci-kpd.md - https://github.com/linux-kdevops/kdevops/blob/main/docs/kernel-ci/linux-modules-kdevops-ci.md If you want to help avoid Linux kernel modules regressions, now its simple, just add a new Linux modules sefltests under tools/testing/selftests/module/ That is it. All new selftests will be used and leveraged automatically by the CI. -----BEGIN PGP SIGNATURE----- iQJGBAABCgAwFiEENnNq2KuOejlQLZofziMdCjCSiKcFAmdGbrcSHG1jZ3JvZkBr ZXJuZWwub3JnAAoJEM4jHQowkoinIDEQAMa1H7hsneNT0Z/YewzOfdSKZIkTzpk3 /fLl7PfWyFvk7yHT1JiUXidS/80SEMnWb+u8Sn00/uvcJomnPcK9oTwTzBQ0vefl FWIUM0DmBzBOi5xdjrPLjg5o6TFt7hVae3hoRJzIlLD02vGfrPYpyHo7XmRrLM4C 8p+3geziwZMpjcGM254eSiTGxNL8z1iZVRsz8QrrBruRfBDnHNgwtmK097v13Xdb qmLX6CN2irmNPZSZwDqP8QL2sJk9qQpNdPmpjMvaY3VfaMVkM46FLy0k9yeXXNqw E1p/GuylCZq4NG1hic9zB1I1CE910ugCztJnPcGw4C7CSm54YoLiUJrIeRyTZhk6 et9N25AlJHxyq72GIRTMQCA9Njxaavx5KilvuWYZmaILfeI0k/3gvcxUqp/EJQ9Q axPu69HJFRSKMVh1o+QrSaPmEtSydpYwuuNJ6ONRpq5I3bzOVDSCroceAdXEMO9K yoSfm4KwN/BSnmX6KVLonrSM91nv2/v9UokuaZMV/CsDpXIZs996PvAoopCm1Twb K3fv0uD+2q2FTOOBInkuRJo2zBUvNnDRPAS2pE3DMXy8xhsQXdovEpjijuCGb8eC y0R+I4RIugIB2n6YBUFfyma1veGlT3PtrWQnO6E3YJpv8bqIJoYVT5IGo9M9YRO9 lzjtR9NzGtmh =Ny84 -----END PGP SIGNATURE----- Merge tag 'modules-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/modules/linux Pull modules updates from Luis Chamberlain: - The whole caching of module code into huge pages by Mike Rapoport is going in through Andrew Morton's tree due to some other code dependencies.
